Sparse Multipath Channel Estimation and Decoding for Broadband Vector OFDM Systems
Qi Feng, Xiang-Gen Xia, Zhihui Ye +1
Vector orthogonal frequency division multiplexing (V-OFDM) is a general system that builds a bridge between OFDM and single-carrier frequency domain equalization in terms of inters…
Artificial-Noise-Aided Message Authentication Codes with Information-Theoretic Security
Xiaofu Wu, Zhen Yang, Cong Ling +1
In the past, two main approaches for the purpose of authentication, including information-theoretic authentication codes and complexity-theoretic message authentication codes (MACs…
Iterative Eigenvalue Decomposition and Multipath-Grouping Tx/Rx Joint Beamforming for Millimeter-Wave Communication
Zhenyu Xiao, Xiang-Gen Xia, Depeng Jin +1
We investigate Tx/Rx joint beamforming in millimeter-wave communications (MMWC). As the multipath components (MPCs) have different steering angles and independent fadings, beamform…
A Coherent Integration Method Based on Radon Non-uniform FRFT for Random Pulse Repetition Interval (RPRI) Radar
Jing Tian, Xiang-Gen Xia, Gang Yang +2
To solve the range cell migration (RCM) and spectrum spread during the integration time induced by the motion of a target, this paper proposes a new coherent integration method bas…
Hierarchical Codebook Design for Beamforming Training in Millimeter-Wave Communication
Zhenyu Xiao, Tong He, Pengfei Xia +1
In millimeter-wave communication, large antenna arrays are required to achieve high power gain by steering towards each other with narrow beams, which poses the problem to efficien…
A Robust Generalized Chinese Remainder Theorem for Two Integers
Xiaoping Li, Xiang-Gen Xia, Wenjie Wang +1
A generalized Chinese remainder theorem (CRT) for multiple integers from residue sets has been studied recently, where the correspondence between the remainders and the integers in…
